Application September 10, 1931, Serial No. 562,134

' 1 claim. (c1. 20s-44) R tion of a simple and efficient' covering or wrapper 1Q for a pie or similar product, wherein the covering or wrapper is held infirm engagement with the container by folding or rolling the edge of the wrapper over the edge of the container, and without the necessity of employing otherJ securing means.

With these and other objects in view, the invention consists in certain novel constructions, combinations and arrangement of parts, as will be hereinafter more fully described and claimed.

Figure 1 is a top plan view of the container with the wrapper secured thereto, and partly broken away to show the position ofthe container and the relative position of the pie or vother food product.

Figure 2 is a section taken on lineq 2-2 o Figure 1.

Figure 3 is a bottom plan view of a portion of the container showing the manner in which the wrapper is rolled under the edge of the container for holding the covering or,wrapper in position.

Figure 4 is a transverse sectional view through a container showing a modified form or manner of securing the wrapper or covering under the edge of the container.

By referring to the drawing it ,will be seen, for the purpose of illustration, that 41 designates a 'container in the nature of a pie plate` having diverging side walls 2 and terminating in a beaded outer edge 3. The pie or other food product 4 is placed within the container l as shown clearly in Figure 2 and over the top of the container and food product placed therein, is placed a sheet of transparent glossy material, such as transparent paper;l cellophane, glassine, or similar material, indicated by the numeral 5. This transparent strip of paper 5 has its ends projecting well over the beaded portion 3 of the container l and the edges or ends of the paperare then preferably rolled or coiled under the beaded portion 3 of the container lto produce a coiled retaining band 6, which snugly ts under the beaded portion 3 of ,the container 1 and holds the transparent paper 5 snugly over the top of of the covering lf2 and prevent the/same from the container and over the top Aof the food product 4.

While it is preferred that the transparent sheet 5 be held in engagement with the container -1 through the medium of the coiled band 6 as il- 60 lustrated and previously described, and while this has been found to bea preferable way, it is not desired to limit this particular application to this particular form of securing the transparent sheet to the container, since .the sheet may be folded at its edges as indicated at7 in Figure 4 to t against the inclined faces ofthe side walls 9 of the container 10 and under the bead portion 11 of the container 10 as shown in the modified form in Figure 4. 70 This sheet 12, as shown in Figure 4, may be spun lor folded back Vunder the side edge and under the bead portion 11 of the container 10 in any suitable or desired manner to restrict the edges accidentally pulling off from the top of the container. The principal Afeature which Vshould be l borne in mind, however, is that the spinning under,-thecoiling under, or tucking under, or folding back of the edges of the transparent sheet will produce a retaining ring whichmay be pressed flat against the container if desired, the wrapper in this way constituting a self-containing closure for the container in which the food product is placed.

It should be understood that by using a package wrapped as described above and illustrated in the drawing, the baker will be enabled to manufacture and deliver a pure and wholesome produst to the customer without any danger of it be- 90 coming soiled or contaminated in transit.

By means of the invention as illustrated and described a better package is produced which is less expensive than any so far attempted and still has the following distinctive featuresz- A 95 Sanitary, not touched by hand, as mechanical means may be provided for its manufacture; .f

Perfect covering and still elastic enough to permit the product to breathe and expand;

Transparent, permitting a visual inspection of kind and nature of content; 1

Glossy surface of the neatly fastened wrapper giving a greater sales appeal;

Economical, minimum amountY of Awrapping used, no glue, adhesive or binding material required. l

Heretofore, with few exceptions, pies and the like have been delivered by bakers to the retailer without any protective covering. A few bakers have placed their products in a special envelope 110 or bag which required an expensive hand operation and a few others wrapped the pie loosely, placed it on a plate so that the weight of the pie would hold the tucked in sides of the wrapper between the pie and plate, again others have wrapped both pie and plate, fastening the tucked under sides by means of some adhesive or binder to the bottom of the plate. l c

By means of the simple device illustrated, it will be seen that no adhesive or other securing means other than the wrapper itself is necessary to seal the upper end of the container. K

It is a well known fact that food products such as pies and the like must not be confined in a closed container. but should be allowed to breathe, thereby permitting the vapors to escape. It is also the nature of this kind of product to grow the flrst few hours after being-baked, and the wrapper must therefore be elastic and expand to take care of the growth.

It should be understood that certain detail changes in mechanical constructions may be 'employed without departing from the spirit of the invention, so long as these changes fall within the scope of the appended claim, and it is not desired to necessarily restrict the present application to the wrapping of food products alone, since the method and structure as well as process illustrated will be found applicable to a large variety of products, sizes and shapes of containers.

In actual practice it is preferable to moisten the wrapper by means of a damp sponge or felt -wick` along the edge of the wrapper which exterial may only require heat to give the desiredl result.v

Having described the invention, what is claimed as new is:

In combination with a container open at its top and having a bottom and walls rising therefrom and formed with an outstanding bead, a single transparent comparatively thin wrapper sheet with unpleated marginal portions, said sheet being stretched across the top of said container with its marginal portions projecting from the container and curled downwardly, inwardly, upwardly and outwardly to form a compact restricted portion tting snugly about walls of the container against the under face of said bead whereby said wrapper will be held against accidental removal from the container and will constitute a shield for the open top of the container.
